Field‐based Forest Carbon Assessment Griffith University, Gold Coast Campus
No full textThe native forests of Griffith University contribute a range of ecosystem services and functions including sequestering carbon, and hence are an important component of Griffith University’s Sustainability Goals including United Nations Sustainable Development Goal (UNSDG) 13: Climate Action and UNSDG 15: Life on Land. To estimate the carbon currently stored within the native forests, and potential for future carbon sequestration, field estimation of the carbon sequestered in the forests on the Gold Coast campus of Griffith University was undertaken in 2023. Specifically, Above Ground Biomass was estimated by converting measurements of the height and width of all woody plants and standing dead trees with a Diameter at Breast Height of at least 5 cm along two randomly located 20 x 50 m transects in the dominant Blackbutt forest Regional Ecosystem (RE) using standard allometric calculations. These field values were then converted to tons of Above Ground Carbon per ha (126 t C ha‐1 ) which was then combined with the current area of intake for the forest on‐campus (29.2 ha) to give a final estimate of the amount of Above Ground Carbon (3,679 t carbon) as well as both Above and Below (in roots) Ground Carbon in woody plants (4,672 t carbon). Furthermore, these forests could be contributing to further carbon sequestration at an estimated rate of 85 t ha‐1 y‐1 . These results demonstrate the importance of the forests on the Gold Coast campus in their role as relatively high carbon stocks when compared to other sub‐tropical forest types in Queensland. It also emphasises their role as carbon sinks when they recover from past logging, and other types of disturbance, with an estimated sequestration of carbon at a rate of 85 t ha‐1 y‐1 . However, they could become a source of carbon (losing more than they sequester) if not appropriately managed, including damage to the few remaining large old trees, which are significant carbon stores, with less than 3% of the trees accounting for more than 52% of the carbon stock on the campus. Inappropriate bushfire management is another important risk that could reduce the sequestration potential of these forests.Full Tex
Field Based Forest Carbon Assessment Griffith University, Nathan Campus
No full textThe native forests of Griffith University contribute a range of important ecosystem services and functions including sequestering carbon, and hence are an important component of Griffith University’s Sustainability Goals including in relation to the United Nations Sustainable Development Goals SDG13: Climate Action as well as SDG15: Life on Land. To estimate the carbon currently stored within the native forests on the Nathan campus of Griffith University, and potential for future carbon sequestration, field estimation of the carbon in the forests was undertaken along 14 transects across 7 of the 12 Regional Ecosystems (RE) on the campus in 2023. Specifically, Above Ground Biomass was estimated by converting measurements of the height and width of all wood plants and standing dead trees with a Diameter at Breast Height of 5cm along 14 10m * 50m transects (two per RE, randomly located) using standard allometric calculations. These field values were then converted to tons of Above Ground Carbon per ha (12.5.3a = 98.1, 12.9‐10.17c = 155.2, 12.9‐10.26 = 168.2, 12.9‐10.4 = 141.3 12.11.24 = 177.2, 12.11.25 = 106.8, 12.11.26 = 94.4, weighted average across RE = 150 t C ha‐1 ) which when combined with the area of each sampled RE and other RE on campus (144.6 ha) to give a final estimate of the amount of Above Ground Carbon (21,749 t carbon) (living and standing dead) as well as both Above and Below (in roots) Carbon in woody plants (living and standing dead) (27,186 t carbon). There were lots of dead standing trees in the forest (20.9% of wood plants). When they were removed from the calculations the carbon values were slightly lower per RE (12.5.3a = 85.1, 12.9‐10.17c = 144.2, 12.9‐10.26 = 161.3, 12.9‐10.4 = 132.3 12.11.24 = 158.5, 12.11.25 = 102.4, 12.11.26 = 64.0, weighted average across RE = 139.4 t C ha‐1 ) while the total Above Ground Carbon in living wood plants was estimated as 20,193 t carbon and both Above and Below (in roots) Carbon in living woody plants was estimated as 25,241 t carbon. These values are broadly similar to those for a range of wet open forests in subtropical Queensland and reflect the generally high BioCondition of the forests at Nathan. It is also possible to estimate carbon flux for the forests on campus based on a rate of 2.92 t ha‐1 y‐1 given for similar forests in the region. Using this value, the Nathan forests may be sequestering carbon from the atmosphere at the rate of 423 t ha‐1 y‐1 . However, too frequent/hot bushfires, further clearing, drought conditions and the spread of weeds will reduce biodiversity in the forests and their capacity as carbon stores and carbon sinks.Full Tex
Field‐based Carbon Assessment of the Arboretum at the Logan campus, Griffith University
No full textForests on the campuses of Griffith University contribute a range of ecosystem services and functions including sequestering carbon, and hence are an important component of Griffith University’s Sustainability Goals including United Nations Sustainable Development Goal (UNSDG) 13: Climate Action and UNSDG 15: Life on Land. This includes the 5.2 ha Arboretum at the Logan campus of Griffith University. To estimate the carbon sequestered in the Arboretum over the initial nine years of growth, field work was undertaken in 2023. Specifically, Above Ground Biomass was estimated by converting measurements of the height and width of all woody plants and standing dead trees with a Diameter at Breast Height (DBH) of at least 5 cm in 10m by 15m randomly located quadrats in each of 28 blocks of forest in the Arboretum using standard allometric calculations. These field values were then converted to tons of Above Ground Carbon per ha (38.9 t C ha‐1 ) which was then combined with area of the Arboretum (5.2 ha trees) to give a final estimate of the amount of Above Ground Carbon (192.5 t carbon) as well as both Above and Below (in roots) Ground Carbon in woody plants (240 t carbon). These results demonstrate the importance of the Arboretum where an open area of grass has been turned into a high biodiverse urban forest consisting of over 3,500 trees in 2023 representing 56 species that is cooling the Logan campus, conserving soil, providing habitat for wildlife and wellbeing benefitsfor staff,students and visitors. It has also already sequestered about 29% (Gold Coast) or 27% (Nathan) of the carbon in the native forests on the other campuses. Ongoing management of Arboretum and other wood vegetation on the Logan campus including trees in the Slakes Creek restoration forests, formal gardens and the small area remnant forest at the Logan Campus of Griffith University will ensure they continue to provide benefits including carbon sequestration.Full Tex

Development of a Crash Prediction Model for Signalized T-Intersections in Queensland, Australia
No full textVehicle crashes at signalized intersections have long been of utmost concern to the transport authorities. Some researchers have developed crash prediction models (CPMs) for roundabouts in Queensland to establish the relationship among crashes, geometric parameters, and traffic conditions. However, to date, no CPM has been developed for the signalized intersections in Queensland. In this dissertation, two CPMs for signalized T-intersections in Queensland, Australia are developed: a CPM at intersection level and a CPM at approach level. The proposed models can be used for better control/organization of the traffic and design intersection geometry/layout.
After the introduction to the dissertation and overview of the relevant research, a geographic information system (GIS)-based spatial database is established in Chapter 3 to visualize the crash records in south-east Queensland. Further, a crash assignment model is developed to assign crashes at signalized T-intersections to distinct approaches on the basis of the GIS-based spatial database. In Chapter 4, a CPM at intersection level is developed to predict the crashes at intersections, given the geometric parameters and traffic conditions. It should be pointed out that the number of lanes, merging angle, and existence of slip lanes are found to be significantly related to crashes.Thesis (Masters)Master of Philosophy (MPhil)Griffith School of EngineeringScience, Environment, Engineering and TechnologyFull Tex
